Abstract

Dorsal rhizotomy from C2 or C3 to T4 in the primate results in failure to elicit summated cortical responses from systematic stimulation of the appropriate peripheral nerves. Under these conditions there is thus no evidence of sensory input into the cerebral cortex. A nonclassical mechanism must therefore be operational to explain the extensive purposive movements observed in the deafferented animals.
